Parinaud's Syndrome or Dorsal Midbrain Syndrome | Also known as the pretectal, or sylvian aqueduct syndromes, it is characterized by paralysis of upgaze to both saccades and pursuit. In this video, the causes of Parinaud's, along with its signs of large pupils with light-near dissociation, spastic-paretic accommodation, pathologic lid retraction (... | Image/MovingImage |

Brain Stem Eye Movement Syndromes | In this series, the importance of the brainstem in eye movements is discussed, with particular emphasis is placed on the signficance of the paramedian pontine reticular formation (PPRF), the medial longitudinal fasciculus (MLF), and the nuclei and projections of cranial nerves III and VI. Correlat... | Image/MovingImage |

Cerebellar Eye Signs | Lesions of the cerebellum can result in a variety of eye movement disorders, including saccadic intrusions and oscillations, such as ocular dysmetria, as well as nystagmus, gaze palsies, and dysfunction of the vestibular ocular reflex. In this series of videos, these disorders are discussed in rela... | Image/MovingImage |

Cerebral Control of Eye Movements | In this series, the purpose and nomenclature of eye movements are described, with the anatomical pathways generating and controlling the cortically-driven movements -- saccades and smooth pursuit in horizontal gaze, upgaze and downgaze -- discussed in detail. The importance of each of the three sac... | Image/MovingImage |
